Rate Rise in November? Stress-Test Your Buy-to-Let First
Buy-to-let mortgage rates are rising again. The average fixed buy-to-let rate climbed from 5.47% in August to 5.79% at the start of October, and some economists expect the Bank of England to raise Bank Rate on 5 November. Before you buy, test the deal at a higher rate. If the rent still covers the mortgage comfortably, it's a deal. If it only works at today's rate, it isn't.
I'm George Samoila. I run Manchester Sourcing, and we buy houses for investors across the North West and the North East of England, most of them living overseas and buying without a viewing. This is how I'd check a deal this week.
Are buy-to-let mortgage rates rising?
Yes. According to Which?, using Moneyfacts data published on 7 October, the average fixed-rate buy-to-let mortgage was 5.79% at the start of October. In August it was 5.47%. That's a third of a percentage point in about two months, after most of the year spent drifting down.
Will the Bank of England raise rates on 5 November?
Nobody knows, and anyone who tells you they do is guessing. What we do know: in September the Bank held Bank Rate at 3.75%, but three of the nine members voted to raise it to 4%. Which? reports that Barclays Research expects a 0.25 point rise in November, and that experts expect Bank Rate to end the year at 4%.
Lenders don't wait for the decision. They price what they expect, which is why buy-to-let rates have already moved. Plan for higher, and treat a hold as a bonus.
How do you stress-test a buy-to-let?
Take the rent, take the mortgage at today's rate, then work out the mortgage again at one percentage point higher. If the rent still covers the higher payment with room left for repairs, insurance and a rainy-day fund, the deal stands up. Here's a worked example.
A typical two-bed terrace in Liverpool costs around £100,000, and leased to a social housing provider it rents for £850–£950 a month (our usual range there). On a 75% interest-only mortgage you borrow £75,000.
6% (what we use for a UK-resident buyer): monthly interest on £75,000 £375; left from £850 rent £475
7% (stress test: +1 point): monthly interest on £75,000 £438; left from £850 rent £412
7.79% fixed for five years (our overseas buyers' lender): monthly interest on £75,000 £487; left from £850 rent £363
8.79% (stress test: +1 point): monthly interest on £75,000 £549; left from £850 rent £301
Even at the stressed rate, the rent covers the interest with room to spare. That's the point of buying in the North.
These are illustrations, not quotes. They're before purchase costs, insurance, maintenance and tax, and your own rate depends on your circumstances and your broker.
What's changed since our October update?
On 1 October I wrote that social housing lenders usually price at around 6–7%. That's still roughly true for UK-resident buyers. For overseas buyers, the specialist lender that funds overseas investors on social housing leases is now at 7.79%, fixed for five years, at 75% loan-to-value, interest-only. That's above the range I gave then, so I'm saying it plainly here.
The upside of a five-year fix is that a November rise doesn't touch it. You know your payment until 2031. The downside: if rates fall, you don't benefit until the fix ends, and there are usually early repayment charges if you sell or refinance before then.
Are northern rents still rising?
Yes, faster than anywhere else in England. The ONS figures published on 21 October show:
Average UK rent rose 3.8% in the year to September 2026, to £1,406 a month.
The North West had the highest rent growth of any English region, at 5.7%.
The North East still has the lowest average rent in England, at £790 a month.
North East house prices rose 3.2% in the year to August, down from 4.7% the month before.
So prices in the North East are cooling a little while northern rents keep climbing. For an investor, that's the right way round.
The bits a rate rise doesn't change
A provider lease protects your income, not your mortgage. The rent is guaranteed for the length of the lease and paid even if the house is empty, which makes the stress test simple: you know the rent figure. But your mortgage can still go up when a fix ends.
What else stays the same:
Your repairs. The provider looks after internal maintenance and tenant damage. The exterior, the electrics, the boiler and the pipework are yours. Boiler cover at about £15–£20 a month takes most of the risk out of the boiler. I covered the full split in who pays for repairs on a social housing lease.
Lease renewals. Leases usually run three to five years and need renewing.
Currency. If you earn in another currency, a swing in the pound can move your returns more than a quarter-point rate change.
What this means for you
Buy on numbers that work at one point higher. If a deal only works at today's rate, walk away.
Think about the length of your fix. A longer fix buys certainty; a shorter one keeps options open. That's a conversation for your broker, not for me.
Don't wait for rates to fall. The Bank is talking about rises. Waiting for a cut could mean waiting a long time while rents rise.
If you're buying from abroad, budget for a 25% deposit, the extra 2% non-resident stamp duty on top of the 5% additional-property rate, and currency risk. Check yours on our stamp duty calculator. For your own tax position, speak to your tax adviser.
FAQ
Will buy-to-let mortgage rates go up in November 2026? They might. The average fixed buy-to-let rate was 5.79% at the start of October, up from 5.47% in August, and Barclays Research expects a 0.25 point Bank Rate rise on 5 November. Lenders often move before the Bank does, so plan for higher rates and treat a hold as good news.
What is a buy-to-let stress test? It's working out the mortgage at a higher rate than you'll pay, usually one or two points more, and checking the rent still covers it. Lenders do their own version before they lend. Doing it yourself first tells you whether the deal survives a rate rise or only works on today's numbers.
Should I fix my buy-to-let mortgage for five years? It depends on your plans. A five-year fix gives you a known payment and protects you from rises, but you won't benefit if rates fall, and leaving early usually costs an early repayment charge. Your broker will weigh it against your own circumstances. I can't give you personal financial advice.
Does a social housing lease protect me from rising rates? It protects your income, not your mortgage. The rent is guaranteed for the length of the lease and paid even if the house is empty, so your income is predictable. But if your fix ends or you're on a variable rate, your mortgage payment can still rise. That's why the stress test matters.
Can overseas investors still get a buy-to-let mortgage in the North? Yes. Many of our investors live abroad and buy without seeing the house. Expect a 25% deposit, a higher rate than a UK resident, the 2% non-resident stamp duty surcharge and currency risk. Our overseas buyers use a specialist lender at 7.79% fixed for five years.
